Abstract

The invention relates to a turbine blade dihedral angle chord width machining device and method. The turbine blade dihedral angle chord width machining device comprises a base, an inclined support is arranged on the base, a supporting column perpendicular to the support is arranged on the support, a connecting rod is horizontally hinged to one end of the supporting column, a swing bolt is arranged at the other end of the connecting rod in a penetrating mode, and the swing bolt is arranged on the base. The other end of the swing bolt is arranged in the support, and positioning balls are arranged on the two sides of the swing bolt. The machining precision of the dihedral angle chord width of the turbine blade can be effectively improved.

Description

technical field [0001] The invention relates to the field of machining turbine blades of aero-engines, in particular to a machining device and a machining method for dihedral angle and chord width of turbine blades. Background technique [0002] At present, the dihedral angle of the guide blade of the aero-engine turbine is processed by the thin-walled positioning of the trailing edge of the blade body. Since the front and rear edge plates of the blade have a certain inclination angle, the radial direction also has an inclination angle. When processing the half-chord width, it is necessary to ensure the relative position between the edge plate and the blade body, and the circumferential direction needs to use the blade in the middle of the blade body as the circumferential positioning point. The current processing methods are all using ordinary fixtures for clamping, and using high-precision five-axis machine tools to process the blades by inverting the angles of the machine...
